REED-ORGAN STOP-ACTION.

SPECIFICATION formingpart of Letters Patent No. 279,372, dated June 12, 1883.

Application filed March 1, 1882. (No model.)

which the following is a specification, referorgan action.

I5..kl1ld have either been located at the side of the ence being had therein to the accompanying drawings. Y

The object of my-invention is to produce an improved mechanism for operating all of the. valves or mutes of areed-organ simultaneously, thus producing what is known as the grand- Heretofore mechanisms of this cell-board, or, if located over the cell-board, l1c ve been *of such nature as to interfere with the octave-coupler and thepush-pins. There has also been much difficulty with the valveoperating mechanisms, when arranged over the cell-board, in causing the valves to be opened sufficiently, while at the same time considerable power has been lost in overcoming the friction caused by the parts sliding one upon the other. These difficulties I overcome by mounting a double-cranked rocking bar directly over the cell-board and between the valves, and connecting the said bar and valves by cords or links in such manner that all the valves will be opened simultaneously and by a direct pull, thus reducing the power required to operate them, these parts being so arranged as in no way to interfere with the other opera tive parts-of the organ, as will be hereinafter described. 7

In the drawings I have shown in Figure 1, in perspective, a portion of an organ sufficiently large to illustrate my invention. Fig. 2 is a top plan view of the same.

A represents the cell -board, B the reedboard, and L the'key-frame blocks.

D D are the valves on the front side of the cell-board for the purpose of opening and closing the sets of reeds on the front side, and O 0 represent the valves which open and close the sets of -reeds on the rear side.

(I d represent the springs which operate to return the valves into their closed position, they being made of any suitable material and arranged in any of the ordinary ways.

I have not shown devices for opening each cords or links I) b.

valve separately, but any of the ordinary stopactions may be used.

This invention pertains more especially to improved devices for opening several of the Valves 5 simultaneously. This simultaneous opening I effect as follows:

.F represents a rocking shaft or rod mounted in the key-board block L, or up on standards K, of which any necessary number may be used,

* each situated up on or in line with the cell-board shaft is rocked. This plate G is connected with the front valves, D D, by means of cords or links I) b. The cords or links are attached to the oscillating plate and the valves in such 7 -manner that when the end 9 of the plate G is 1 moved upward the valves D D shall be opened by means of the intermediate cords or links. I) I) represent similar cords or links attached at one end to the opposite side or end, 9, of plate 7 G, and at the other end connected to the rear valves, 0 O, by means of small uprights or standards E E, secured to said valves. When the plate G is rocked so as to throw the end downward from the position shown in the draw- 8 ings the valves 0 0 will be opened through the By connecting the rear valves or mutes, O O, and the plate G, as shown, the cords or links I) b will lie close to the cellboard, in such position that they will not in- 8 terfere with the octave-coupler, and so they can easily pass between the push-pins n. (See Fig. 2.)

In the drawings I have shown the rocking bar F so mounted as to leave space for the 00- 9 tave-coupler between the line of push -pins and the rear valves, 0; but when it is desired to place this mechanism between the push-pins and the front valves, D, the bar F will be mounted back of the push-pins, instead of in 9 front, as shown. In this case the cords b I) would lie close to the board, instead of the cords b b.

If desired, adjusting devices may be combined with the cords or links, whereby the proper tension may be exerted upon the cords, and wherebyjhe points of attachment of the links may be adjusted, so that the valves shall always open at the proper times.

In practice I prefer to make the connecting parts I) b and b b of cord, as the cords are easily attached to the part G- and the valves, their lengths can be easily and accurately adjusted, they are much cheaper than wood or metal, and they occupy but little space, while they perform their operations as satisfactorily as when these parts are made of other rigid material.

The rod 11 is rocked, and with it the plate (1- is oscillated, by means of a crank-arm, H, carrying a projecting pin or stud, d, and alever, K, vibrating in vertical planes below the stud or pin (1. \Vhen the lever K is raised (which raising may be accomplished by any of the ordinary mechanisms used for kindred purposes in organs) it engages with the pin or stud d, which, through the c 'ank-arm H, rocks the shaft F and plate G, throwing the end 9 upward and the end 9 downward, which results in the simultaneous opening of the valves D D and O C.

By using devices of the nature above described '11 avoid the disadvantages and the trouble from interfering with the coupler mechanism which have been incident to the devices heretofore employedin grandorgan actions. I also avoid the complicated mechanism which has been tried heretofore, and provide a simple, cheaply constructed, but effective grand-organ action.

Of course it will be understood that in several matters the devices shown might be modifiedwithout departing from the spirit of my invention.

That I claim is 1. The combination, with the valves (J and I), of the rocking bar having part G, and mounted between the valves upon the cell-board, the said part G being oscillated by said bar, and the connections I) 1) between the part G and the valves, substantially as set forth.

2. The combination of the valves (3 and 1) upon opposite sides of the cell-board, the puslt pins passing through the cell-board, the rock.- ing bar F, mounted directly upon thecell-board between the valves, having cranks extending in two directions from the axis of the bar, adjustable devices passing through the series of pins connecting one of the cranks with the valve 0, other adjustable devices connecting the other crank of the bar F with the other valve, D, substantially as set forth.

3. In a reedbrgan, the combination, with the cell-board ha ving a series oi'pusl1-pins passing through it, of the valves or mutes D and G, situated, respectively, at the front and rear of the cell-board, a double-c ranked rocking bar, F, mounted upon the cell-board, between the push-pin and one of said valves, and cords or links I) b, one of which, b, lies close to the cellboard and passes through the series of pushpins, substantially as and for the purposes set forth.
